I was hoping to spend more money on tires but it did not work out that way. The Shinko 230's seem to be made well and the rubber every bit as sticky as the old Pirelli Phantoms use to be way back in the day according to my finger nail
Its going to take a bit before I can install them. First I need to finish building this motor.
Just got back on this project the other day after spending a lot of time on another bike.
Getting back to fixing a F'd up crank bolt hole on the upper case.
Getting it clamped to my tiny milling machine was going to be some work.It was a couple of hours of trial and error until I used the uprights from my exhaust stud drilling fixture which have the same angle cut as the top surface of the upper case.
Quite a bit of a struggle but I knew it was not going to be easy.
Have it clamped securely and used a drill bit to position the 3/8 end mill where it needs to be to do the tap drill hole. Looks like it will clean up most of that angled crap in there now.
Here is the modified 7/16-14 X 1-1/4" bolt
Needed to use a end mill as the hole in there was oval. 3/8 is tap drill size for that thread (that is why I picked it) I just used the drill chuck as I had to swap out some tools on the same locked center.
Here is the modified bolt with a M8 blind thread in it sunk into the fixed threaded hole. Put some 3 Bond about 1" down and some red Loctite at the top.
Cut off the hex head with a angle grinder and thin cut off disk.
Finished insert spot faced with a 7/16" end mill to be flush with top of mating surface.
Now I have proper oil flow without leaks and a solid steel M8 thread for my crank bolt.

I was going thru my engine bolts needed to assemble this motor, was looking to clean and de grease them.
The crank bolt that was in that messed up hole was not a Kawasaki bolt so I was looking to replace it. Looked up the part number for the M8 x 81mm flange head bolt, still available but for +$15 = YIKES!!
Remembered that I replaced the crank bolts in my 1327 drag bike engine with APE studs, so those extra bolts were here somewhere. Spent the better part of a hour looking for them to finally finding them plus some other goodies I forget I had. At least I don't have to pay $$ to Kawasaki for one
Filled both pry slots on upper case with JB Weld, will file flat once hard. This needs to be done as its very thin in the area around those to properly seal the base gasket.
The top bolt hole that attaches the points housing got filled the other day, a short bolt goes in that one, this keeps oil from seeping out.
These steps are not necessary if you stay below 1135cc. It gets worse at 1327cc, a window opens up on the generator side.
